Reverse osmosis equipment is mainly used in the process of various membrane water treatment, simple equipment may be directly called reverse osmosis equipment, complex equipment called reverse osmosis system. The use of reverse osmosis equipment, will inevitably surface scaling weather, not only difficult to clean, but also affect the results of water production. So, reverse osmosis equipment scaling weather in the end is caused by what causes it? The actual fact is that you can find out how to solve it.

The actual water in the reverse osmosis membrane, insoluble salts will stay in the membrane name, into solid precipitation precipitation. In the process of reverse osmosis equipment operation, the pressure generated in the process of low-pressure flushing will produce fresh water, and the concentration of water on both sides will naturally deepen, deepen at the same time will lead to the concentration of salt deepening, salt contains a large number of precipitable substances, a long time will appear scaling weather. Therefore, only insoluble salts do not exceed the limit of satiation can effectively prevent the occurrence of scaling. In the design aspect, in order to better replace the concentrated water, may try to ensure that the concentrated water contains low salt content.

The main insoluble salts in the natural water supply are: calcium carbonate, barium sulfate, calcium sulfate, calcium fluoride, strontium sulfate and silicon dioxide. When designing the reverse osmosis system, special attention should be paid to barium sulfate and strontium sulfate. The increase in the concentration of calcium sulfate and the fall in water temperature will also lead to a decrease in the solubility of strontium sulfate.

In addition, some inorganic substances that are not high in the natural body of water can be brought into the feed water because of artificial factors, such as dosing, for example: phosphate, iron and aluminum and other inorganic salts often have a very low solubility product, prone to scaling, so when the system is filled with pharmaceuticals (such as flocculants, coagulants, scale inhibitors, acids and bases, etc.), take into account the impact of these artificially introduced ionic components.
